I'll just say this - there are private implementations of Keccak that blow the pants off of those numbers. Keccak is one of the primary functions in Ethash (Ethereum mining). It is heavily researched and completely destroys SHA2 performance-wise if you have the right implementation. Also, Keccak doesn't require the construction of a key-schedule, and can be implemented much more elegantly in parallel (SIMD software) and in hardware than SHA2.
